  sun4u: switch m48t59 NVRAM to MMIO access
  MAINTAINERS: add myself as SPARC maintainer
  doc: minor updates to SPARC32 and SPARC64 documentation
  m48t59: add m48t59 sysbus device
  m48t59: introduce new base-year qdev property
  m48t59: let init functions return a Nvram object
  m48t59: add a Nvram interface
  m48t59: register a QOM type for each nvram type we support
  m48t59: move ISA ports/memory regions registration to QOM constructor
